Abstract

Improved real-time automated motorist information around workzones can help relieve congestion and improve safety around those workzones. Several Automated Workzone Information Systems (AWIS) are being deployed around the nation. The California Department of Transportation (Caltrans) requested that The California Center for Innovative Transportation (CCIT) evaluate the Computerized Highway Information Processing System (CHIPS), which is an AWIS developed by ASTI Transportation Systems. The system is able to detect traffic congestion (using its traffic sensors) in the work zone area and then deliver appropriate messages to motorists (via its port~ble message signs) as they approach or pass through a work zone.
